Put, the suction nozzle that can solve adsorbent equipment blocks and inhale hypodynamic problem, improve the stability of adsorbent equipment, lifting work effect
Rate.
The purpose of this utility model is achieved through the following technical solutions：A kind of novel chip suction nozzle, including positioning head, suction nozzle
Body and sorption channel, one end face of the suction nozzle body are provided with adsorption head, and the positioning head is fixed on the another of suction nozzle body
One end face, sorption channel runs through the suction nozzle body and positioning head, it is characterised in that：The adsorption head is provided with multiple vacuum
Hole, described each vacuum hole is connected with the sorption channel respectively.
Wherein, positioning shaft shoulder is additionally provided with suction nozzle body, positioning shaft shoulder is installed on the suction nozzle body, and is provided with positioned at it
Rotation stop plane on circumference, locating slot is provided with the relative position of the rotation stop plane.
Wherein, the width of locating slot is 2.04mm.
Preferably, the end face of adsorption head is the square of length of side 4.9mm.
Wherein, the vacuum hole number is five.
Wherein, five vacuum holes are divided into centre bore and four vacuum holes being symmetrically distributed in around it.
Wherein, the radius of centre bore is 1.5mm.
Wherein, the radius 0.5mm of other four vacuum holes.
Wherein, the depth of vacuum hole is 2mm.
Wherein, the distance of centre bore axis described in rotation stop plane separation is 7mm.
The beneficial effects of the utility model：
A kind of novel chip suction nozzle of the present utility model, including positioning head, suction nozzle body and sorption channel, the suction nozzle sheet
One end face of body is provided with adsorption head, and the positioning head is fixed on another end face of suction nozzle body, and sorption channel is through described
Suction nozzle body and positioning head, the adsorption head are provided with multiple vacuum holes, the multiple vacuum hole respectively with the sorption channel phase
Connection, adsorption head is provided with multiple vacuum holes, and is symmetric on the end face of adsorption head, and vacuum hole connection is through positioning
The sorption channel of head and suction nozzle body, inhales vacuum plant and chip to be measured is adsorbed onto into adsorption head by sorption channel and vacuum hole
On, by increasing the vacuum hole of suction nozzle and the contact area of chip to be measured, the constant feelings of vacuum pressure are produced vacuum plant is inhaled
Under condition, increase chip lifting surface area so as to improve chip suction, while be provided with multiple vacuum holes also reduce vacuum hole be blocked and
The situation for making suction nozzle to work completely, improves the stability of suction nozzle work.
